SPECIFICATION forming part of Letters Patent No. 358,788, dated March 1, 1887.

(No model.)

To all whom it may concern.-

Be it known that I, ELZIDAS RAINAUD, a cit-izen oftheUnited States,residing at Jamestown, i the county of Chautauqua and State of New York, have invented a new and useful Improvement in Machines for Rounding or Beveling the Insoles of Boots or Shoes, of which the following is a specification.

My invention relates to an improvement in machines for rounding or beveling the insoles of boots or shoes; and it consists in the peculiar construct-ion and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a machine embodying my improvements,

, end of the standard is a vertical slotted opening, D.

E represents the d riving-shaft, which isjournaled in openings that are arranged at right angles to the slot D,and intersect the center of the same. To the central portion of the driving-shaft is attached a large pulley, F, which works in the opening 1), and to one end of the shaft is attached a fast driving-pulley, G, and a loose idle-pulley, H.

I represents a head, which is provided on its under side, at the center, with a depending shank, K, which fits in the socket G, and thus swivels the head on the upper end of the standard. A set screw, L, passes through an opening in one sideof the upper end of the standard and bears against the shank K, thus permitting the head to be adjusted vertically and secured at any desired position. The head is provided with vertical arms or standards M, having bearing-boxes at their upper ends, in which is j ournaled a horizontal shaft, N. To that portion of the shaft which is between the arms or standards M, and directly in vertical line with the pulley F,is attached a pulley, O.

This is connect-ed to the pulley F by an endless belt, P. To one end of the shaft N is attached an emery-wheel, R.

S represents a pair of circular cutting-disks, which are beveled on their opposing sides,and are provided with peripheral beveled notches T, thereby forming radial cutting-shouldersU at the inner ends of the said notches. These circular cutters are secured on one end of the shaft N, a suitable washer, V, being inter-' posed between them, and on opposite sides of the circular cutters are secured guards WV, which comprise the radial webs or spokes X and the rims Y, which project inwardly over the edges of the circular cutters. The said cutters and the guards are secured firmly to the shaft N and rotate therewith in the direction indicated by the arrow in Fig. 1.

The operation of my invention is as follows: The operator grasps an insole which is to have its edges beveled or rounded, and presses the edge of the insole between the opposing faces of the rotating cutters and moves the insole so that the cutters operate entirely around its edges. The cutters serve to bevel or round the edges of the insole on opposite sides, and the guards prevent the insole from moving laterally between the cutters,and thus cause both sides of the insole to be beveled or rounded alike. The guards also serve a useful purpose in preventing the fingers of the operator from accidentally coming in contact with the rap idly revolving cutters and being injured thereby.

WVh en it is desired to bevel the edge of an insole only upon one side, this may be accomplished by removing the outer cutter from the shaft Nand reversing the same on the shaft, so that the plane face of the outer cutter will be opposed to the beveled face of the inner cutter.

Heretofore, so far as I am aware, it has been the custom to trim or bevel the edges of insoles by hand, and it requires a skillful workman to turn out fifty pairs of insoles in an hour. My machine for trimming and beveling the edges of insoles is capable of turning out two hundred pairs of insoles in an hour, and it performs the work better and more uniformly than it can be done by hand.

The object of beveling and rounding the insole is to prevent the edge of the insole from ICO cutting or otherwise injuring the shoe-upper. Having thus described my invention, I claim-- 1. In a machine for trimming and beveling 5 the edges of insoles, the circular rotating cutters arranged in pairs and having the beveled cutting-shoulders on one side, the other side being plane, the said cutters being reversible,for thepurposesetforth,substantiallyasdescribed. 2. In a machine for trimming and beveling the edges of insoles, the circular rotating cutters having one side plane and the opposite side beveled at the rim and provided with the cutting-shoulders, in combination with the circular guards having the webs to bear snugly against the outer sides of the cutters, and the annular broadened rims projecting inwardly over the edges of the cutters, substantially as described.

3. In a machine for trimming and beveling the edges of insoles, the circular rotating cutters arranged in pairs, having the plane bev eled opposing cutting-sides to trim the opposite edges of theinsoles, substantially as described.

4. In a machine for trimming the edges of insoles, the combination of the standard A, having the rotating pulley F, the head vertically adjustable on the said standard and having the shaft N, provided with the pulley 0, connected to the pulley F, and the herein-described circular cutters arranged in pairs and attached to the shaft N, substantially as described.

In testimonythat I claim the foregoing as my. own I have hereto affixed my signature in presence of two witnesses.

ANDREW P. QUIGLEY.
